Timmy and his fairies were staring with their mouths open at a floating green portal in Timmy's bedroom. Jimmy Neutron had just appeared shortly after Danny and his friends left, surprising everyone.

"Well don't just stand there with your mouths agape!" Jimmy exclaimed. "I have urgent news that will affect not only Retroville but Dimmsdale and Amity Park as well!"

"Wait a minute," Wanda interrupted. "You know Amity Park?"

"A city full of ectoplasmic entities?" Jimmy said, the sarcasm evident in his voice. "There are many cities and dimensions I've discovered over the years, Amity Park being one of them. I knew Danny was inherently good which is why I decided to come and play a part in his rescuing."

"What do you mean? It was his friends who helped him," Wanda said.

"Indeed, but without Cosmo and Poof's return to Fairy World, Danny would have succumb to his dark side," Jimmy explained.

"It was you!" Cosmo said. "You released us from the Master's mansion!"

Jimmy nodded. "As well as returning your Big Wand back to its upright position after it had been knocked down once again. I was watching and only helping where necessary."

"But why?" Wanda asked.

Jimmy sighed. "I have been getting strange readouts from each and every dimension I've ever found, some higher than the others. At the time yours was the most pressing so I decided to look on and see if you needed assistance."

"Well thanks, uh, I think," Timmy said. "But something bad happened, didn't it?" Timmy asked. "It usually does when you're involved."

"Hey!" Jimmy shouted. "I could have selected to engage in otherwise entertaining activities, but instead I chose to help you." Looking resigned Jimmy composed himself and looked to Timmy with honest eyes. "But I do come to you for help myself."

"What kind of help?" asked Wanda, an eyebrow raised.

"It's best if we discuss things here," Jimmy said gesturing to his lab. "I temporarily moved a section of my dimension portal to your world so I could contact you but it won't last long."

"Don't worry, I got this," Timmy said. He turned to his fairies and said, "I wish we were in Retroville!"

Instantly Timmy and his fairies poofed to the lab of Jimmy Neutron. Timmy looked at his hands and feet. "I'll never get used to this bulgy universe."

Jimmy turned around and faced the quartet. "Ah, perfect!" Jimmy grabbed Timmy and placed him in his chair. What Timmy saw next was quite shocking indeed. "You see these three screens are the alternate universes I've been to. Each one has a readout that is off the charts as you can see on the screen."

"Uh, that red-bar thingy?" Cosmo said looking at the screen as though hypnotized.

"The scientific term, Cosmo, would be the BPR (Breaking Point Readout)," Jimmy explained. If it ever gets past the red and goes into black…well it's lights out for that particular universe."

Timmy looked over to the bottom left and saw Dimmsdale. The BPR was at yellow, the first bar. There were three other screens though that still had high signals. "Where are these places?" Timmy asked. "They seem more odd than Retroville."

"The first screen you see is showing us a cul-de-sac filled with children our age. The parents are seemingly never around so they always seem to get up to all sorts of shenanigans. But something's been happening in the cul-de-sac that has me worried and it needs to be investigated," Jimmy explained.

"Right," Timmy said. "And what about that second screen? It looks like Halloween."

"Ah yes, Endsville. I've actually been there and let me tell you, you wouldn't want to be caught there alone. But it does have high readouts that I cannot ignore for much longer," Jimmy stated. "I definitely need assistance if I am to go to Endsville."

"What about that last one?" Wanda asked, straining her eyes. "It just looks like an abandoned farmhouse."

"That farmhouse is the property of Eustace and Muriel Bagge, who live in Nowhere, Kansas. I scanned their farmhouse and found some fairly decent technology and obtained a great deal of information in doing so. The information is rather odd but helpful. Something looms in Nowhere and it needs our attention," Jimmy said.

"Wait, our attention?" Timmy said. "No, no, no. I did NOT sign up for this!"

"Come on Timmy, Jimmy needs our help," Cosmo said. "He may be a fudgehead, but he's OUR fudgehead!"

Timmy huffed and puffed but finally agreed. "Fine, I'll do this. But there's someone I want to contact first."

Jimmy smiled, grateful for his friend's help. "Gladly."
